Inside your abdominal muscle, peritoneum, a kind of soft tissue, holds your internal organs in place. If for some reason, an organ pushes through an opening or a soft area in the peritoneum, the condition is called hernia. It is usually visible in the form of a bump in the area. Depending on the location and extent of displacement, it can be either painless or painful, harmless or harmful. However, painlessness in such a condition doesn’t necessarily mean that it is harmless.
